I have a 10MB fibre point to point leased line. I've been running iperf over it and getting speeds between 5MB-7MB, does this seem right to you? This was tested by plugging a laptop directly in at each site

7mb is reasonable but not the full 10mb... iperf is a great little tool...

Point to point Fiber should be pretty much right at 10mbit but overhead will eat up a bit... but fiber latency and overhead is managed over your 10mbit limit usually. Fiber gets handled differently than copper circuits depending on the carrier obviously.

I'd also sniff what is going over that link because if you have any other domain network traffic flowing at the same time your iperf will be affected...

Unplug all other network connections while testing... that should get a true number...

Remember your conversions, it isnt 10MB connection it is probably a 10Mb connection. then you have to consider overhead and whether or not the line is quiet. But first make sure you are using consistent units, that could be throwing things off.
